Acid mine, drainage (AMD) due to the oxidation of sulphide bearing waste rock (WR) is a common environmental problem associated with ,coal, extraction. Therefore, WRs from the Lakhra ,coal, field in Pakistan, were studied to i) perform a mineralogical and chemical characterisation, ii) determine the AMD generating potential and iii) estimate the leachability of elements.
